Hi, I am trying to dynamically add IP_Options to the packet header in 2.6.23 kernel to perform strict source routing. I am using Netfilter hooks (NF_IP_LOCAL_OUT hook) to intercept the packet before it goes out of the host. If the IP_Options are set through setsockopt() in my application, I am able to read those options using Netfilter. However, I am not sure how to insert new IP_Options into packets originating from another application. Could anyone please point me to some documentation or sample code regarding this. Thank you, Ashwini. - To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
